Php Laravel Composer更新不'；不及格

我使用的是Laravel 5.0，我需要用于我的工作，但在更新Composer后，我出现以下错误：

My

composer.json

：

{
“名称”：“laravel/laravel”，
“说明”：“Laravel框架”，
“关键词”：[“框架”、“拉威尔”]，
“许可证”：“麻省理工学院”，
“类型”：“项目”，
“要求”：{
“laravel/framework”：“5.0.*”，
“照亮/html”：“5.*”，
“laravelcollective/html”：“5.2.*”，
“maatwebsite/excel”：“~2.1.0”
},
“需要开发”：{
“phpunit/phpunit”：“~4.0”，
“phpspec/phpspec”：“~2.1”
},

},

]
},
“配置”：{
“首选安装”：“dist”
}
}

我应该如何处理我的Laravel？

在版本5.2.*中不能将laravelcollective/html与Laravel 5.0.*一起使用，因为前者要求后者至少为Laravel 5.2.*

这与maatwebsite/excel不兼容无关。

听起来您正在运行的PHP版本不符合Laravel 5的要求。最小版本为“php”：“>=5.5.9”。你可以通过执行

php-v

来检查你的

composer.json

文件吗？我会尝试删除你的composer.lock文件并重新安装数据库文件夹中有什么？我注意到作曲家有一个类映射到它
